I think you’ll find that the majority of hardware synths/grooveboxes out there do not export stems or multichannel audio into a DAW.
Overbridge is one of those “pro” features that you get in the Digi line and higher, rather than the entry-level Models.
There is Underbridge - which is a third-party tool designed to automate the process of importing each track individually (rather than multi-tracking) from the M:C/M:S and OP-Z; but I have no experience with it, and I’m not sure what a license costs.
